I've got a very simple test setup that I can't seem to get to work:
I draw a simple spline in Unreal (4.18) (Actor + Spline component).
I have an HDA (H 16.5.268) that marshals that spline via the World Outliner Input and an Object Merge in Houdini.
The HDA sets the normal of the incoming curve's points to {0,1,0} (point wrangle).
Then copies a box to each point (copy to points).
In Houdini this looks fine: all boxes are aligned vertically.
In Unreal it works EXCEPT the alignment is along the curve tangent.
I've made no other changes and using all other defaults.
If I expose an editable Curve from Houdini to Unreal it works as expected.
If I use the Curve Input and re-create the curve in Unreal it works as expected.
Is this a bug or am I missing something?
Thank you.
